Potential for (unexpected) strong signal received by PMTs when changing axes

[delmic]

On the SPARC, when doing live view of a PMT (eg, CL intensity or Monochromator), if the user changes filter or center wavelength, there is a potential that during the move a strong signal is received. That's because while the move happen, on the filter wheel other filters (such as pass-through) can be temporarily active, and allow more signal to go through, or on the spectrograph, a peak could be situated between the initial and target position of the center wavelength move.

Possible solutions:

• Stop acquisition during the moves
• Activate the protection during the moves
